G. E. BURSON INTERNAL COMBUSTION ENGINE FiledNov. 24. 1925 2Sheets-Sheet 2 [Luis-Ll inder 12 is caused to rotate by the crank shaftwhich is rotated by the piston rod It will be readily understood thatany other mechanism can be employed for rotating the cylinder, but thismechanism is preterably operable by the piston rod so that the enginewill be properly kept in time;

Any suitable timing.- mechanism can be employed for causing the tourspark plugs 35 to tire in proper order.

The operation of the engine is as follows: Referring particularly toFig. 3. the pistons are in the extreme right hand side position. Theport 38 on the right hand side of the piston 25 is opposite the inletport 30, and fuel is drawn into the cylinder 12 between the piston 25and the partition 23 while the piston 25 is moved toward the left. Thefuel which was previously admitted to the cylinder between the pistonand the closure 15 is compressed durine' this stroke. At the same timethe piston an on the right hand side of the partition 23 is opposite 1tsexhaust port 33 and the burned gases between the piston 26 and thepartition 23 are being discharged through it. The port :36 on the rightof the piston 26 is opposite its spark plug 35 which is tiring at thisinstant so that there is occurringan explosion or burning of fuelbetween the piston 26 and the closure 14, lOlClllfl the piston rod 22toward the left. When the piston rod reaches its extreme left position.the cylinder will have been rotated 90 deg. so that the port 36 which isshown on Fig. 3 as being opposite its spark plug just uncovering itsexhaust port 3 3. The exhaust port 36 which is on the extreme lett handend of the cylinder is uncovering its sparlc plug 35 and there isoccurring an explosion between the piston 25 and the closure 15. forcingthe piston rod toward the right. lhis nuwement of the piston toward the.right compresses the l'uel between the piston '25 and the partition 23.exhausts the exhaust gases between the piston 26 and the closure 14, andcauses Fuel to be drawn into the cylinder from the port 29 to the spacebetween the partition 23 and .the piston 26. During the second movementfrom the extreme right position to the left of the cylinder. theexplosion occurs between the piston 2.3 and the partition 32?. theburned gases are exhausted from between the piston .35 and the closure15. the fuel between the piston 2t and the partition 23 is con'ipressed,and tucl is being drawn into the space botween the piston 26 and theclosure l t through the inletport During the second movement from theextreme left hand position of the cylinder to the right fuel is drawninto the space between the closure 15.

and the piston 25. the burned gases between the piston 25 and thepart1tion 23 are being exhausted, the compressed tuel between theseason? piston 96 and the partition 23 being fired and compression istaking place between the piston 26 and the closure 14.

By this construction it will be appreciated that the new internalcombustion engine is of the four cycle type and that the complete deviceis embodied in a single rotatable cyl inder. l*urthermore, as thecylinder is com pletely surrounded by a water cooled housing. it will bectl'ectively cooled and wear and heat will be evenly distributed.

It will be readily understood that any desirable lubricating system canbe employed for luln'icatingz the moving surfaces between the cylinder'and the housing. the cylinder and the piston and the piston rod. Suchlubricating system is preferably provided with a force pump for forcingthe oil to the surfaces to be lubricated. which force pump is preferablydriven by the crank shaft.

It will be understood that various changes may be made in the detail ofconstruction without departing from the spirit or scope of the inventionas defined by the appended claims.
